ZIGCAM vs TrackOSC
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
ZIGCAM
This app transforms your iPad or iPhone into a device that transmits real-time depth and camera data using NDI. It integrates seamlessly with development environments like Unreal Engine and broadcast applications such as OBS, allowing you to utilize LiDAR depth data and ARKit information in your preferred PC applications.
- Real-time NDI data transmission
- Emulates iPad/iPhone as data source
- Utilizes LiDAR depth data
- Supports ARKit data
- Integrates with TouchDesigner and Unreal Engine
- Secure and simple operation

ZIGCAM is an application for building virtual production prototypes and new visual production workflows. Using NDI and NDI metadata, it emulates the iPad and iPhone as devices capable of transmitting depth data and camera data in real time. Because it uses NDI, it can be used out-of-the-box with various development environments such as TouchDesigner and Unreal Engine, as well as broadcast applications such as OBS. With Tablet or Smartphone, you can use LiDAR's highly accurate depth data along with camera images in your favorite PC application. This application is also very simple and secure. This application will allow you to receive the following information to your PC or other device for as long as you want, but will stop all communication the moment you press the "Sending!" button in the application. ・Camera Data ・True Depth (Face Tracking) ・Smoothed Depth (LiDAR) ・Estimated Depth ・Various other ARKit data ZIGCAM provides real-time Face Tracking functionality using the TrueDepth API, but we do not collect, use, disclose, share, or retain any of this data.
TrackOSC
This app transforms your iPhone into a wireless motion-tracking camera. It streams real-time pose, face, text, and animal tracking data over your local network as OSC messages. All processing is done on-device, ensuring your video never leaves your phone.
- Live tracking overlays (body, hand, face, text, animals)
- Per-detector toggles for performance
- Front/back camera support with selfie mirror
- Portrait/landscape orientation lock
- Automatic OSC receiver discovery (Bonjour)
- Hide-video mode for stage use

TrackOSC turns your iPhone into a wireless motion-tracking camera. Point it at a person and it streams live tracking data – body poses in 2D and 3D, hand poses, face landmarks, recognised text, animals, people, barcodes, outlines, the horizon and rectangles – over your local network as OSC (Open Sound Control) messages, ready for TouchDesigner, Max/MSP, Processing, openFrameworks, Pure Data, SuperCollider, Unity, or anything else that speaks OSC. All processing happens on-device with Apple's Vision framework. No video ever leaves your phone – only numbers. WHAT IT TRACKS • 2D Body: a 17-joint skeleton in pixels • 3D Body: a 17-joint skeleton in metres – real depth from a single camera, with each joint's pixel position alongside • Hand: 21 joints per hand, up to two hands • Face: the face box, head rotation and jawline contour, and Face Landmarks: the full 76-point constellation – eyes, pupils, brows, nose, lips, jaw • Text: recognised text with its bounding box • Animal: cat and dog boxes, and Animal Pose: full 25-joint cat and dog skeletons • Human: whole-body boxes that keep counting people at distances where pose estimation gives up • Barcode: QR codes and 1D/2D barcodes with position, corners, symbology and payload • Contours: every edge outline in the frame as closed polylines • Horizon: the horizon's angle and a line across the frame • Rectangles: screens, paper, doors – a box plus four corners FEATURES • Live tracking overlays on the camera view, colour-coded per detector • One chip per detector – run just what you need for the best frame rate; 3D Body runs in its own lane so it never slows the others • Front or back camera, with a natural selfie mirror (wire data is never mirrored) • Portrait and landscape, with an orientation lock for phones mounted on tripods and rigs • Automatic discovery of receivers on your network via Bonjour – or type any IP and port • Hide-video mode: tracking overlay only, on black – for stage and installation use • Free, notarised macOS companions – a Receiver with 2D and 3D views, a Recorder that records and replays the stream, a Speaker that reads it aloud, and a Router that turns it into MIDI, Shortcuts, key presses and HTTP – plus open-source receiver examples for Processing, Python, p5.js, TouchDesigner, Max/MSP, Pure Data, openFrameworks and SuperCollider, all from the project page COMPATIBILITY TrackOSC speaks exactly the same OSC wire format as VisionOSC and PoseOSC, so existing receivers and patches work unchanged. The newer detectors arrive as additional messages that older receivers simply ignore. Coordinates are in pixels, origin top-left, with the frame dimensions in every message. PRIVACY No accounts, no analytics, no ads. Camera frames are analysed on the device and discarded; tracking data is sent only to the destination you choose. TrackOSC is open source: https://github.com/JGL/TrackOSC

Verdict
ZIGCAM and TrackOSC both sit at 5.0 stars, but that hides the real split: 100% of TrackOSC's written reviews are positive against 50% of ZIGCAM's. TrackOSC also leads on in-app purchases (none vs 1). ZIGCAM's advantage is device support (3 vs 1) and iOS requirement (14.1 vs 18.0). On price, rating, ratings volume and update cadence there is nothing between them.
